“…The present study also revealed that the overall slide positivity rate of malaria was low (i.e., 3%), but higher among males (i.e., 84.8%) and non-Malaysians (i.e., 47.8%). These results are similar to those of studies conducted in the same setting in 2003 [18,19]. With regards to gender, previous studies in Malaysia also showed that males had a higher percentage of malaria cases compared to females, possibly due to occupational exposure, which involves mainly forestry and plantation [4,14].…”

“…Our finding also revealed that 16 out of 29 confirmed malaria cases from Southeast Asia were from Myanmar's patients. As of January 2021, of the approximately 164,620 refugees and asylum-seekers registered with the United Nations High Commissioner for Refugees (UNHCR) in Malaysia, 86.5% were from Myanmar, 67% were males, and 16.8% of them had resettled in Kuala Lumpur [19]. As Malaysia moves toward elimination, malaria will begin to cluster among certain high-risk groups, including migrants and displaced populations.…”

While there has been a tremendous decline in malaria disease burden in the remote parts of Malaysia, little is known about malaria incidence in its urban localities. This study aimed to analyze trends of malaria cases in urban Kuala Lumpur, Malaysia. All suspected cases presented to a university hospital in Kuala Lumpur from January 2005 to December 2020 were examined by microscopy. Infection status was analyzed using descriptive statistics and curve estimation analysis. Of 3105 blood films examined, 92 (3%) were microscopically confirmed malaria cases. Plasmodium vivax infections accounted for the majority (36.9%) of all malaria cases. Nearly half (47.8%) of cases were found among foreign cases (p < 0.001). The majority of foreign cases were male (86.4%) and came from Southeast Asian countries (65.9%). The curve estimation analysis showed significant decreases in malaria cases due to P. vivax (R2 = 0.598; p < 0.001) and Plasmodium falciparum (R2 = 0.298, p = 0.029), but increases for Plasmodium knowlesi (R2 = 0.325, p = 0.021) during the 16 years. This study showed that malaria incidence in urban Kuala Lumpur is low and has remained stable since 2005. However, P. knowlesi has played a significant role in the increase in overall malaria in the area, highlighting the importance of continued vigilance and improved surveillance.

“…Despite the significant decrease in human malaria, the emergence of simian malaria is a major public health problem in the less developed areas of Malaysia. In particular, it is a problem among the hard-to-reach indigenous populations (i.e., Orang Asli) in Peninsular Malaysia and the remote interior communities in Malaysian Borneo [3,5,7,8]. In 2019, Malaysia recorded 3222 zoonotic malaria with six fatalities [9].…”

“…Furthermore, the influx of migrant workers from malaria-endemic countries and challenges of drug resistance have exacerbated the risk of re-emergence of the disease. Due to the large-scale clearing of forest areas for logging and agricultural purposes, Malaysia faces the problem of increasing cases of simian malaria driven by the migration of macaques to human settlements, particularly in the remote areas where the aboriginal populations live [3,5,8,10]. Although Malaysia has been recognized as one of the countries free from indigenous human malaria since 2018 [1], it is essential to acknowledge the prevalence of non-human malaria and strengthen the effectiveness of the national elimination program.…”

Malaria remains a public health problem in many parts of the world, including Malaysia. Although Malaysia has been recognized as one of the countries free from indigenous human malaria since 2018, the rising trend of zoonotic malaria, particularly Plasmodium knowlesi cases, poses a threat to public health and is of great concern to the country’s healthcare system. We reviewed previously scattered information on zoonotic malaria infections in both Peninsular Malaysia and Malaysian Borneo to determine the epidemiology and distribution of emerging zoonotic malaria infections. Given the high prevalence of zoonotic malaria in Malaysia, efforts should be made to detect zoonotic malaria in humans, mosquito vectors, and natural hosts to ensure the success of the National Malaria Elimination Strategic Plan.
